The Whitland73 has a cast iron enamel interior and an aluminum exterior with an air gap in between, this is excellent for heat retention. The interior enamel is gloss white which provides a superb contrast to the exterior eggshell surface. FinishingThe exterior of the tub is a metal surface which has been cleaned and smoothed after forming and had an epoxy primer applied. Three coats of high grade single stage eggshell onyx black paint are then applied to complete. The surface is very easy to maintain and clean, just a simple wipe with a dry cloth. The interior of the tub is hand applied enamel. As a result, slight undulations will appear on the surface and this will add to the individual character of every Penhaglion Hand Finished bathtub.
